> I assume if their consumer facing AI is using Claude at all it would be a Sonnet or Haiku model from 1+ versions back simply due to cost.

I would assume quite the opposite: it costs more to support and run inference on the old models. Why would Anthropic make inference cheaper for others, but not for amazon?

There may well be some "interesting" financial arrangements in place between the two. After all, Claude models are available in AWS Bedrock, which means Amazon are already physically operating them for other client uses.
